Celebrity Big Brother has been thrown into chaos as two stars have pulled out just days before the launch date.

John Leslie - the former Blue Peter presenter - and transgender rights activist and journalist Paris Lees are believed to have quit and now panicking bosses are struggling to find two personalities to fill their spaces in the house.

According to The Sun, the pair were lined up to become housemates in Britain’s most watched home, but things fell apart at the end of negotiations.

A source told the paper: “Paris’s deal broke down during last minute negotiations, so she won’t be going into the house anymore.

“And John was offered a big, six-figure deal but turned it down and now he’s out of the running too.

“It’s left frantic bosses scrambling to fill the remaining slots.

“They want to land big names but they’re really up against it with time.

“There’s just over a week to go which isn’t long to work out contracts and fees.”

Meanwhile Ryan Thomas has addressed claims he was considering pulling out of CelebrityBig Brother because he didn't want to share a pad with Dan Osborne.

"He was playing hardball and saying it was either Dan or him, but Celebrity Big Brother bosses stood firm and he eventually backed down. Now they're both doing it," a source alleged to The Sun.

Former TOWIE star Dan previously dated Ryan's current GF, Lucy Mecklenburgh, which will no doubt make for some awkward conversations.

However a spokesperson for Ryan said this story wasn’t true: “"It’s ludicrous. Ryan hasn’t even met Dan, and if they were to enter the house together Ryan would be fine with it.”

We’ll find out exactly who quit - and who’s staying on the line-up - for real on August 16, when it launches.
